N=S(P-V)-F. Solve for the S

Likurg_2 [28]

Answer:

$S=\dfrac{(N+F)}{(P-V)}$

Step-by-step explanation:

The given equation is :

N=S(P-V)-F ...(1)

We need to solve the above equation for S.

Adding F both sides in equation (1)

N+F=S(P-V)-F+F

N+F=S(P-V)

Dividing both sides by (P-V). So,

$\dfrac{(N+F)}{(P-V)}=\dfrac{S(P-V)}{(P-V)}\\\\S=\dfrac{(N+F)}{(P-V)}$

So, the above is the expression for S.
